关于Oracle RMAN里面的Merged Incremental Backups的机能，RMAN使用的比较多的DBA们可能会有所了解。
基本上，每次都实行同样的Backup命令即可完成BACK。
列：
Daily Script:
run {
allocate channel oem_disk_backup device type disk;
recover copy of database with tag 'ORA$OEM_LEVEL_0';
backup incremental level 1 copies=1 for recover of copy with tag 'ORA$OEM_LEVEL_0' database;
}
关于上面的Merged Incremental Backups的机能的详细动作，可以参照下面的MOS文档。
[参考情報]
RMAN: Merged Incremental Backup Strategies (Doc ID 745798.1)
=====================
Default behavior for Merged Incremental Backups
First Execution, Day 1: The 'recover copy' command will show ' no copy of datafile 1 found to recover' as this is the first execution
and no level 0 backup existing. The 'backup incremental....' command will make a new level 0 copy as there is no existing level 0.
★第一天，Daily Script的命令会生成一个 level 0 的 copy，会出现' no copy of datafile 1 found to recover'这样的出力。
Second Execution, Day 2: The 'recover copy' command will show 'no copy of datafile 1 found to recover' as there is still no previous level 1 backup.
The 'backup incremental...' command will create a level 1 datafile backupset.
★第二天，Daily Script的命令会生成一个 level 1 的 datafile backupset.，也会出现' no copy of datafile 1 found to recover'这样的出力。
Third Execution, Day 3: The 'recover copy' command will recover the level 0 image copy and displays 'recovering datafile copy fno=....'.
The 'backup incremental....' command will create a new level 1 datafile backupset.
★第三天，Daily Script的命令会新生成一个 level 1 的 datafile backupset.，会出现' recovering datafile copy fno='这样的出力，第二天取得的level 1 会Merge到 level 0 的 copy里面。
Future Executions: Each backup taken after the 3rd should show the same behavior as in backup on Day 3.
=====================
通常情况下，上面的例子就可以应用到很大部分的场景。
但是有一个问题，就是Tag。
有一些用户需要用两种Tag分别取得Backup.
即：
RUN
{
allocate channel c1 type disk format '/home/oracle/%U';
RECOVER COPY OF DATABASE
WITH TAG 'incr_update_A';
BACKUP
INCREMENTAL LEVEL 1
FOR RECOVER OF COPY WITH TAG 'incr_update_A'
DATABASE format '/home/oracle/%U';
}
RUN
{
allocate channel c1 type disk format '/home/oracle/%U';
RECOVER COPY OF DATABASE
WITH TAG 'incr_update_B';
BACKUP
INCREMENTAL LEVEL 1
FOR RECOVER OF COPY WITH TAG 'incr_update_B'
DATABASE format '/home/oracle/%U';
}
这种时候，会出现Tag没办法分辨的问题。也就是说
1.incr_update_A执行,生成COPY
2.incr_update_B执行，生成COPY
3.incr_update_A执行,生成LV1的backupset
4.incr_update_B执行,正常情况下，我们期待会生成incr_update_B Tag的LV1的backupset，但是会出现开始Merge的情况。
上面的事项是有回避方法的。

RMAN: Merged Incremental Backup Strategies (Doc ID 745798.1)
=====================
Another image copy can be made back to lag the recover using 'SYSDATE-x' for the 'recover the copy' command.
The
only caveat is the tag being used and another incremental backup is
required using the tag for the copy you wish to
recover. ★
RECOVER COPY OF DATABASE WITH TAG 'MIB_LEVEL_0' UNTIL TIME "SYSDATE-8" FROM TAG 'MIB_LEVEL_0'; ★指定方法 ⇒ FROM TAG
=====================
下面是具体的回避方法。
（不好意思，标注是日语的，不过相信不懂日语的DBA们看到测试结果也会明白）
